A trench map is a graphic depiction of military movements undertaken during trench warfare. It is a basic topographical map overlaid with the location of opposing trenches. Typically they are large scale and show all known aspects of the enemy.

The National Library has a good collection of First World War trench maps at various scales. Mainly British, there is also a small collection of French and German trench maps. The Collection of Edgeworth David's Maps also holds engineering maps which were used for the design and siting of trenches and tunnels.

Although covering the main theatres of war in Europe, France and Belgium, there is a small coverage of Gallipoli, Israel and Palestine.

Books held at the Library which can provide background on the development and use of trench maps include:
